Sulphureum Barrenwort

Sulphureum Barrenwort (Epimedium x versicolor 'Sulphureum')

Sulphureum Barrenwort (Epimedium x versicolor 'Sulphureum') is a classic shade perennial prized for soft, nodding sprays of pale sulfur-yellow flowers in mid to late spring and handsome, heart-shaped foliage that emerges bronze to copper, matures deep green, and often blushes red in fall. Forming a slowly spreading, drought-tolerant clump, it is an elegant problem-solver for dry shade, under trees, and woodland borders.

Distinctive Features

Abundant, long-spurred yellow blossoms carried on wiry stems above the leaf canopy; spring foliage flushes bronze and adds color before bloom; semi-evergreen in mild climates; naturally deer and rabbit resistant; excellent tolerance of dry shade once established.

Growing Conditions

• Soil: Humus-rich, well-drained soil; thrives in loam amended with leaf mold or compost.
• Water: Moderate; keep evenly moist the first season, then water deeply during prolonged dry spells.
• USDA Hardiness Zones: 5 to 8.
• Mature Size: About 8 to 12 inches tall in leaf, 12 to 16 inches in bloom, spreading 18 to 24 inches over time.

• Mulching: Apply 2 to 3 inches of leaf mold or compost to conserve moisture and enrich soil.
• Feeding: Light spring top-dress with compost or a balanced slow-release fertilizer.
